Al’in is the online rental platform of Action Logement that centralizes offers of social and intermediate housing reserved for employees in the private sector. Its operation is based on a linkage with the national social housing application file: the employee does not need to recreate a complete file, as their data is automatically imported via their unique application number (NUR or NUD). This technical architecture changes the way people search for housing from a smartphone.
Linking the national file and automatic filtering on Al’in
The uniqueness of Al’in compared to a simple catalog of listings lies in its direct connection with the portal demande-logement-social.gouv.fr. The employee submits their application on this national portal, obtains their unique number, and then enters it into Al’in. The platform then retrieves the information from the file (income, family composition, geographical area) without manual re-entry.

This mechanism has a direct consequence on the mobile experience: the application only displays offers compatible with the employee’s profile. No sorting through hundreds of unsuitable listings. The display is filtered upstream, which reduces the time spent searching on a phone screen.
To understand how the Al’in application for employees works, it is important to keep this overlay logic in mind: Al’in does not replace the official application submission; it complements it by adding offers from Action Logement’s partner landlords.

Mobile search criteria: location, income, and family situation
On mobile, searching for housing via Al’in is not limited to a “city” field and a “search” button. The platform cross-references several parameters related to the employee’s daily life.
- The geographical location allows targeting an area close to the workplace or a specific living area, not just an administrative municipality.
- The financial resources of the household, already provided in the national file, filter offers according to the income ceilings applicable to social or intermediate housing.
- The family composition determines the type of housing offered: a couple with two children will not see the same offers as a single person.
This automatic cross-referencing prevents the employee from applying for offers for which they would be ineligible anyway. On a phone, where navigation is less comfortable than on a computer, this pre-selection significantly reduces the number of clicks needed before finding a relevant listing.
Eligibility and access to Al’in: the role of employee status
Al’in is not open to all social housing applicants. Access is conditioned by the status of an employee in the non-agricultural private sector. The company must contribute to the PEEC (Employer Participation in the Construction Effort), historically known as “1% Housing”.
When creating the account, the employee provides additional information related to their company. This employer-employee link is verified before the reserved offers become visible. Without this step, the account remains active but without access to the listings from partner landlords.
Social housing and intermediate housing: two categories on the same platform
Al’in displays two types of properties. The classic social housing, subject to strict income ceilings, represents the majority of the stock. Intermediate housing is aimed at employees whose incomes exceed the social ceilings but are still insufficient to access the private market without difficulty.
On mobile, both categories appear in the same stream of results, filtered according to the profile. The employee does not need to switch between two interfaces or two separate applications.

Application and scoring on Al’in: what happens after applying
Applying for an offer from their smartphone takes a few minutes, as the file is already established via the national file. Supporting documents (tax notices, employment proofs) are submitted online on the application portal and then synchronized with Al’in.
One point that traditional user guides rarely mention: applications are not processed in the order they are received. Al’in uses a point scoring system. The scoring takes into account criteria such as the seniority of the application, family situation, or income level relative to the ceilings. This ranking means there is no advantage to applying in the first minutes after an offer is published.
Each offer remains visible for a limited time (up to two weeks according to sources). The employee can therefore consult new listings at their own pace, without the pressure of “first come, first served” that is found on private rental platforms.
Updating the Al’in file: an often neglected obligation
An Al’in account without an up-to-date file becomes unusable. Each year, the employee must update their reference tax income on the national registration site, submit their latest tax notice, and then confirm the update in Al’in.
Without this update, access to offers is blocked. On mobile, the update notification may go unnoticed if the employee does not log in regularly. Checking the status of their file at the beginning of the calendar year remains the most reliable precaution to avoid an interruption of access to listings.
Al’in concentrates in a single interface the link between the national file, employee status, and offers from partner landlords. The time-saving on mobile comes less from the app’s ergonomics than from this layered architecture, which eliminates redundant steps even before the employee initiates their first search.
